\paragraph{Input arguments}\label{input-arguments}

\begin{itemize}
\item
  \texttt{X} {[} tseries {]} - Input times series.
\item
  \texttt{W} {[} tseries \textbar{} numeric {]} - Fixed or time-varying
  weights on the input time series.
\item
  \texttt{Range} {[} numeric {]} - Range on which the Divisia index is
  computed.
